It’s from the Bible.
Abraham’s nephew Lot was pulled from Sodom before its annihilation by fire. Later, prophets referred to those saved from destruction as being “snatched from the flames.”
Also, evil kings of Israel sacrificed their living children to demons as burnt offerings. Today, aborted children’s remains are medically incinerated. Child sacrifice continues.
Although those speak of destruction, I believe a loving God, through the atoning work of Jesus Christ, brought the purifying fire of the Holy Spirit into our lives, to refine, guide and ultimately change the world to the glory of God the Father.
“And I will bring the third part through fire, refining them like silver, testing them like gold. They will call on my Name and I will answer, saying ‘These are my people’ and each will say ‘The LORD is my God.’ ” -
